(Not available on Ti100 & Ti400 Models)6.1 Primary Loop PlumbingCirculating Pump Due to the Trinitydesign, the boiler is more restrictive than aconventional boiler, thus greaterconsideration must be given to thecapabilities of the circulating pump(s) inthe primary-loop (including the IndirectHot Water heater loop-pump).The following is a listing of therecommended circulators.ModelRestrictionHead LossRecomme ndedPipe SizeMinimumFlow (usGPM)Max.

Ensure that thedischarge of the pressure relief is piped to a location were steam or water won’t cause personal injury or appliance and property damage.The Ti100-150ASME and Ti400 have a maximum operating pressure of 80PSI (145PSI on some models, check the ASME plate affixedto the heat exchanger), therefore a relief valve with a higher relief setting can be used.Boiler Venting: Hot water boilers are designed to operate with airless water in the system. An Air Scoop, installed as shown in thefollowing diagrams, must be installed to remove air as it circulates through the boiler. It is recommended that an additional Air Scoop beused in the secondary plumbing. If air continues to be a problem an air scrubber must be used (recommend Spirovent # VJR 100TM forTi100-150, VJR 125TM for Ti200, and VJR 150TM for Ti400. Use a minimum 1-1/4” primary-loop plumbing with model VJR 125TMand 1-1/2” primary-loop plumbing with model VJR 150TM).
